2. A vertical shutter with less travel distance.
I'm not sure there's any free lunch here. With a shorter travel
distance, the acceleration/deceleration forces would necessarily be
greater for a given shutter speed. I think the amount of energy
released, which is free to cause sympathetic or harmonic vibration
elsewhere, would be similar for similar masses.
It may be that the total mass (actually, moment of inertia) of the
metal shutter is less than the cloth shutter mechanism, and that may
be more important than the travel distance.
There is a lot of speculation on my part in these responses. I'm hardly an
mechanical engineer.
Same here, but it's fun to speculate, no? :-)
